1.RS-485 Communication:<br />
(1)1 vs 1 Controlling: to control one inverter by a PC or PLC or controller.(set 13-0 = 1~254)<br />
(2)1 vs more Controlling: to control more than one inverters by PC or PLC or Controller (The max<br />
number of inverter could be 254. set 13-0 = 1~254), when the inverter receives the communication<br />
station code = 0, the communication controlling is acceptable regardless the setting value of 13-0.<br />
2. RS-232communication: (RS232 interface is required)<br />
1vs1 controlling: to control one inverter by a PC or PLC or controller. (Set 13-0 = 1~254)<br />
※Note:<br />
a. The BAUD RATE (13-1) of PC (or PLC or Controller) and the one of the inverter should be set as<br />
the same .Communication format (13-2/13-3/13-4) should be set as the same.<br />
b. The inverter will confirm the parameter efficient as PC modifies the parameter of the inverter.<br />
c. Please refer to the 7300CV Communication PROTOCOL.<br />
14-0: Stator Resistance(Ohms) Gain<br />
14-1: Rotator Resistance(Ohms) Gain<br />
14-2: Equivalent Inductance(mH) Gain<br />
14-3: Magnetized Current(Amps AC) Gain<br />
14-4: Ferrit Loss Conduction (gm) Gain<br />
Parameter Group 14 - Auto Tuning<br />
1. If 0-00=0 or 1(vector mode ) is selected, as power ON, set 0-06=1, the motor will run as the<br />
inverter performs auto tuning. As the motor stop, it means that auto tuning finished. The inverter<br />
will write the internal parameter of the motor to 14-0~ 14-4, and auto reset the 0-06 as 0.<br />
2. Auto tuning must be carried out as long as the motor changed. If the internal parameters is known<br />
already, they can be input to 14-0~14-4 directly.<br />
3. 0-06=1,to perform auto tuning, after finished, 0-06 auto reset to 0, the Keypad displays END.<br />
4.The parameter group only affect the current vector.<br />
